A 110 g hockey puck slides across the frictionless surface of an ice rink at 2.2 m/s. It collides with a 420 g water bottle at rest on the ice. The water bottle slides off at 0.84 m/s in the direction of the puck's original velocity. What is the puck's final
velocity?

What is the length x of the side of the triangle below? (hint: use the cosine function)

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
